During complex open abdominal aortic surgery, transient clamping of the renovisceral arteries may be required to successfully complete the vascular repair. Endovascular shunting (endoshunting) presents an alternative technique for managing such temporary renovisceral ischaemia. This study aimed to investigate the performance of endoshunting to the renal circulation in a porcine model.</div></div><div><h3>Methods</h3><div>This study of five domestic pigs investigated arterial volume flow rates during endoshunting of a single renal artery and the associated impact on renal perfusion parameters (laser Doppler renal parenchymal perfusion, renal oxygen extraction, and selective urinary output). The study was performed in three steps: baseline registrations (30 minutes), endoshunting (120 minutes), and restoration (60 minutes). The right kidney was used as the experimental side and the left kidney as control.</div></div><div><h3>Results</h3><div>The median arterial flow rate in the left control kidney remained constant throughout the experiment. On the right (endoshunted) side, the baseline median arterial flow rate was 267 (range, 160–404) mL/min. Following activation of the endoshunt, the median arterial volume flow dropped by 59%–110 (range, 45–150) mL/min (<em>p</em> = .018). During endoshunting, the median kidney surface perfusion decreased to 42% of the baseline value. On the control side, a rise in the median parenchymal perfusion was observed after endoshunt activation, which was again normalised following restoration of native right renal artery flow. During endoshunting, the median regional urine production was 0.32 (range, 0.12–0.50) mL/hour but resumed after renal artery flow restoration.</div></div><div><h3>Conclusion</h3><div>On average, the endoshunted kidneys showed a rapid restoration of blood flow, parenchymal perfusion, and urine production after 120 minutes of endoshunting. This suggests that endoshunting to the kidney using an endoshunt system might be a promising strategy to preserve renal function when temporary interruption of native renal artery blood flow is needed during complex vascular surgical repairs involving the renal arteries.</div></div>","PeriodicalId":36502,"journal":{"name":"EJVES Vascular Forum","volume":"62 ","pages":"Pages 104-109"},"PeriodicalIF":1.4,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142698607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, post-operative complications, such as endoleaks and sac growth, can occur, potentially leading to serious consequences. Endoleaks, characterised by persistent flow within the aneurysm sac after repair, can cause sac expansion, increasing the risk of adverse outcomes, including the formation of cutaneous fistulae, a rare but potentially severe complication.</p></div><div><h3>Report</h3><p>A 75 year old male with a history of previous bilateral PAA exclusion with a left femoropopliteal bypass using reversed great saphenous vein (GSV) graft in 2012 and a right femoropopliteal bypass using a PTFE prosthesis in 2017, both through medial approach, presented with pain and ulceration in the left popliteal region. Previous angiography had shown residual arterial flow through collateral vessels, requiring thrombin injection. Bilateral bypass thrombosis had also occurred after discontinuing anticoagulation. Computed tomography angiography confirmed a complicated excluded left popliteal aneurysm with superinfection. The patient underwent elective surgery, involving partial aneurysmectomy, endoaneurysmorrhaphy, and fistulectomy through a posterior approach. Post-operatively, the patient experienced resolution of symptoms and inflammatory signs.</p></div><div><h3>Discussion</h3><p>The optimal approach for treating PAAs remains a subject of debate, with some experts advocating the posterior approach to prevent sac growth. However, others support the medial approach, reporting satisfactory results. In this case, the medial approach resulted in incomplete exclusion, leading to sac expansion and a cutaneous fistula. Timely re-intervention through the posterior approach successfully resolved the complication. This report highlights a rare but serious complication of incomplete PAA exclusion. Vigilant post-operative surveillance and intervention are crucial to manage such cases effectively. Further research is warranted to determine the optimal approach for PAA repair and prevent associated complications.</p></div>","PeriodicalId":36502,"journal":{"name":"EJVES Vascular Forum","volume":"61 ","pages":"Pages 77-80"},"PeriodicalIF":0.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666688X24000522/pdfft?md5=060a06649afe7a00897c3ffb5eb60c72&pid=1-s2.0-S2666688X24000522-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139828424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seven type IIIb EL were related to suture disruption or suture–fabric abrasions. Four cases were related to stent–fabric abrasions, and two developed as a result of fabric fatigue owing to kinking.
